Introduction to 3 Dimensional Geometry

The world we live in is not a 2-dimensional entity that we usually study in coordinate geometry. In fact, there is a third axis to this graph, which makes the objects around us 3-dimensional. A ball, a book, a pen, a table, a car, and even your own body are 3-dimensional. In this chapter, we will be introduced to the coordinate system and coordinate plane of a 3-dimensional graph, finding distances between 2 points in space and dividing lines internally and externally in space.
